Background: Palliative spine radiation therapy is prone to treatment at the wrong anatomic level. We developed a fully automated deep learning-based spine-targeting quality assurance system (DL-SpiQA) for detecting treatment at the wrong anatomic level. DL-SpiQA was evaluated based on retrospective testing of spine radiation therapy treatments and prospective clinical deployment.

- - Since 2014, around 7.3 million Venezuelan migrants/refugees have fled their country, with female migrants facing heightened risks of discrimination and violence, especially during pregnancy, which has been under-researched.
- - In a study utilizing Spryng.io’s sensemaking tool, 9339 micronarratives were collected from 9116 participants across Peru, Ecuador, and Brazil, focusing on the experiences of 231 pregnant migrants identified within the data.
- - Results showed that many of these women are low-income, often already mothers, and face significant challenges, including xenophobia from healthcare providers, various forms of violence, and lack of essential resources, highlighting the urgent need for improved support and programming for this
Purpose: Women remain underrepresented in radiology and there is a paucity of literature examining the recognition of their professional contributions to the discipline. The purpose of this study was to examine the gender distribution of award winners across all North American radiology societies.
Methods: The gender distribution of 1923 award recipients from 21 North American radiology societies between 1960 and 2021 was examined.
Purpose: Oligometastatic disease has expanded the indications for nonspine bone stereotactic body radiation therapy (NSB SBRT). We investigated whether optical surface monitoring systems (OSMS) could enable tattoo-less setup and substitute for 2-dimensional/3-dimensional or cone beam computed tomography (CBCT)-based mid-imaging in NSB SBRT.
Methods And Materials: OSMS was incorporated in parallel with an existing workflow using pretreatment CBCT and 2-dimensional/3-dimensional kV/kV mid-imaging beginning November 2019.
